Description Matt Rogers 2011-08-16 21:11:15 UTC
Description of problem:
With fuse 2.8.3-3.el6_1, trying to unmount an sshfs mountpoint using 'fusermount -u /mnt/point' results in the error "fusermount: failed to unmount /mnt/point: Bad address:

Using fuse 2.8.3-1.el6 does not exhibit this behavior.

The current workaround is to either use umount or stay on 2.8.3-1.el6

Version-Release number of selected component (if applicable):
fuse-2.8.3-3.el6_1

How reproducible:

1. Mount sshfs:

# sshfs 10.12.53.162:/media /mnt/fuse/
root@10.12.53.162's password: 

# mount | grep fuse
10.12.53.162:/media on /mnt/fuse type fuse.sshfs (rw,nosuid,nodev,max_read=65536)

2. Unmount

# fusermount -u /mnt/fuse/
fusermount: failed to unmount /mnt/fuse: Bad address

Additional info:

For the sshfs filesystem I'm using fuse-sshfs-2.2-1.el6.rf from rpmfusion.
